acutis glandulosis subasquilongis disco aequalibus ; paleis inter flores 

 nullis. — On the coast at Shelter Cove and at Fort Bragg, Humboldt 

 Co., Bolander. " Forming large patches or tufts ; the stems lying on 

 the ground, only the heads rising above the grass." Ascending stems 

 or branches a foot or less high, covered like the foliage with the floc- 

 cose cottony down of the genus. Leaves £-2 inches long. 6-10 

 lines wide, thin. Heads 1J- inches or more in diameter, including the 

 numerous violet-purple rays. The narrowest-leaved specimens might 

 pass for the broadest-leaved form of the variable C. jilaginifolia, but 

 the heads are like those of C Californica, only still larger. From the 

 habit, the white-cottony leaves, and the showy heads of flowers, this 

 would be a very desirable acquisition to the gardens. 



Aster Chilensis, Nees, common about San Francisco, was doubt- 

 less collected in California by Hrenke, and not in Chili, where, appar- 

 ently, it does not occur. So that Nuttall's name, A. Durandi, distrib- 

 uted with specimens, but not published, had better be substituted. 



Aster (Orthomeris, Torr. & Gr., Xylorhiza, Nutt.) Andersonii 

 (Erigeron, Celmisia, Andersonii, supra, 6, p. 540) : lana tenui mox 

 decidua glabratus ; caulibus e rhizomate nudo adsurgente erectis sim- 

 plicissimis monocephalis ; foliis gramineis linearibus coriaceis saepe 

 nitidis 3-5-nerviis (angustioribus fere uninerviis), radicalibus spitha- 

 maeis, caulinis brevibus in bracteas subulatas sensim decrescentibus ; 

 capitulo nudo hemisphaerico (^-f poll, lato) ; involucri subtomentosi 

 squamis lineari-lanceolatis acutis subherbaceis laxis 2 - 3-seriatis sub- 

 aaquilongis ; ligulis oblongis (caeruleis vel purpureis) ; styli ramis fl. 

 herm. longe tenuiter subulatis, parte hispida terminali quam stigmatosa 

 3 _ 4-plo longiori : acheniis oblongis villosis 4 - 6-costatis ; pappi setis 

 subaequalibus barbellulatis. — Nevada, Carson City, Dr. C. L. Ander- 

 son. California, Lake Tenaya in the Sierra Nevada, alt. 8,000 feet, 

 Prof. Brewer. Westfall's Meadows in the Yosemite, 8,000 feet, and 

 in meadows on the Tuolumne, 9,700 feet, smaller and smoother speci- 

 mens, H. N. Bolander. The form from the highest station has the 

 radical leaves only 2 to 4 inches long and barely a line wide ; the 

 others of Bolander have the slender flowering stems 6 to 9 inches high, 

 and the conspicuously nerved Xyris-like radical leaves 2 lines wide. 

 Not satisfied with my former reference of this plant to Erigeron, 

 I now perceive that its pappus is neither scanty nor uniserial, and 

 that it must rank with Nuttall's Xylorhiza, Aster Xylorhiza, Torr. & 

 Gray Fl.
